the latches 23 might be made of sheet-metal, or of any other construction, their upper ends being formed with notches 24 adapted .to snap around the loops 22 on the casing.

Having now described the construction and arrangement of my improved device in explained.

detail its methods of operation will next be Normally thc crumb-trays l5 are held in closed relation, as illustrated in Fig. 2, and by grasping the handle 5 the operator moves the sweeper back and fortlr sweeper back and 'forth across the surface to be cleaned the crumbs or other particles are quickly gathered up and when it is desiredI to empty the accumulation it is a very simple matter as follows: To dump the crumb-trays 15 the sweeper' is" held over a waste receptacle and the trays allowed to drop downwardly as illustrate-d in Fig. 3.

To release the trays it is only necessary topress on the opposite sides or' the casing 2 to disengage the loops 22 from the latches 23. This is accomplished most conveniently by holding the casing of the sweeper in the hand with the thumb and fingers pressing against its opposite sides. A slight pressure of the fingers 1s sulhcient to spring the sides of the casing 2 inwardly whereby to release the loops 22 from the notches 2a in the latches 23, and the traysl will then drop bf gravity to empty their contents. After the sweeper has "been cleaned in this manner to prepare it 'for operation again it is only necessary to swing the trays l5 back into closed relation and their latches 23 Maaate will automatically lock with the detent loops 22 to hold them in place.

lt will be observed that my improvement provides a particularly simple and efficient device for the purpose specified, and that its operation is automatic both in its function of sweeping up crumbs, and as regards its self-dumping or emptying feature. Various modifications might be made in the form and structure of the device without departing from the spiritor scope ofthe invention and therefore I do not Wislrto limit my claims to the exact embodiment herein shown. I claim and ,Wish to secure by Letters Patent of the United States:

1. In a 'crumb-sweeper, the combination of a. sheet-metal casing (having an arched top adapted to be grasped on its sides between the thumb and fingers of the hand, a rotary brush in said casing, crumb-trays hinged to the casing to allow them to drop to empty their contents, and detent-rneans on the inside of the casing arranged to hold the trays in close relation therewith, said detent-means adapted to be released by the pressure of the thumb and fingers against the sides ot' the casing.

2. ln a crumb-sweeper, the combination ot a spring-metal casing, a rotary brush in the casing, crumb-trays hinged to the easing to allow them to drop to empty their contents, and de'tent-rneans on the sides of the casing for maintaining the trays in operative relation, said detent adapted for release by pressure on the sides of the casing to release the trays to allow them to drop.

3. ln a crumb-sweeper, the combination ot a spring-metal casing having resilient sides, a rotary brush in the casing, crumbtrays hinged to the casing to allow them to drop to empty their contents,J latches for holding the trays ,in operative position, and detents on the sides of the casing for engaging the latches, said detents adapted to be released from the latches by springing the sides of the casing inwardly.

in testimony whereof I aiix my signature.
